- NetworkAddress now contains IPAddress object which can be either IPv4 or IPv6 address. 128bits are used even for IPv4 addresses, however only 32bits are used when using/serializing IPv4 address. - ConnectPacket is updated to store IPv6 address. Backward compatible with old format since the first 32bits of IP address field is used for serialization of IPv4. - Mainly updates rest of the code to use IPAddress structure instead of plain uint32_t. - IPv6 address/pair ports should be represented as `[ip]:port` as per convention. This applies to both cluster files and command line arguments.
